Testing practices refer to the methods and techniques used to evaluate the functionality, performance, and reliability of software or products. These practices ensure that the final product meets the required standards and performs as expected. Common testing types include unit testing, integration testing, and user acceptance testing, each serving a specific purpose in the development process. Effective testing practices involve planning, executing, and documenting tests to identify defects and improve quality. Automated testing tools can enhance efficiency by running repetitive tests quickly. By implementing thorough testing practices, organizations can reduce risks, save costs, and deliver better products to their customers.
